Brushing and flossing daily, and dental visits at least twice a year: These are the essential things you should be doing to protect your teeth and gums against dental disease. But you're also getting an automatic assist from your body through saliva, that humble fluid swishing around in your mouth, to protect your oral health.
It's more than simply “mouth water”: Without saliva and its various components, your risk for tooth decay or periodontal (gum) disease would be much higher. Here are 4 ways saliva helps you keep your teeth and gums healthy.
Cleansing. Chewing prepares your food for digestion, but in the process produces tiny particles of food debris. Settling on tooth surfaces, these bits become part of the dental plaque that forms on your teeth and develops the ideal breeding ground for disease-causing bacteria. Saliva helps rinse away much of this debris—particularly sugar, the primary food source for bacteria.
Protection. Saliva is the first line defense against disease-causing microorganisms entering the mouth. The primary source of this protection is a protein-based antibody called Immunoglobulin A (IgA), which directly fights infection-causing organisms. Another protein in saliva, lactoferrin (also found in tears), interferes with bacterial growth.
Buffering. The main enemy of tooth enamel is mouth acid, produced by oral bacteria and the foods that we eat. Saliva neutralizes acid to help the mouth maintain its normally neutral pH range. And it works fast: Saliva can buffer acid and restore balance within thirty minutes to an hour after eating.
Re-mineralization. It's normal for acid to build up after eating, and for it to quickly remove minerals from surface enamel, a process called de-mineralization that can soften and weaken the enamel. But saliva helps restore some of these lost minerals as it's neutralizing acid. This re-mineralization re-strengthens enamel against tooth decay.
Saliva is so important for maintaining a healthy mouth, it's worth your efforts to protect it. Diminished saliva production not only produces an unpleasant dry mouth, it may increase your risk for disease. If this is a constant problem, speak to your dentist about causes and remedies. You'll be doing your teeth and gums a favor.

It's normal for people to breathe through their nose. And for good reason: Nasal breathing filters contaminants, warms and humidifies incoming air, and helps generate beneficial nitric oxide. Chronic mouth breathing, on the other hand, can trigger a number of harmful effects, especially for the teeth and gums.
Because our survival depends on continuous respiration, our bodies automatically seek out the air flow path of least resistance, normally through the nose. But if our nasal passages become obstructed, as with enlarged adenoids or sinus congestion, we may involuntarily breathe through the mouth.
This can lead to oral problems like chronic dry mouth, which not only creates an unpleasant mouth feel, it also produces the ideal environment for dental disease. And, it could cause an even more serious problem for children during jaw and teeth development.
This is because the tongue rests along the roof of the mouth (palate) while breathing through the nose. In this position, the tongue serves as a mold for the upper jaw and teeth while they're growing during childhood. During mouth breathing, however, the tongue moves away from the palate, depriving the jaw and teeth of this molding effect, and possibly resulting in a poor bite.
You can prevent these and other oral problems by seeing a healthcare professional as soon as you notice your child regularly breathing through their mouth. The best professional for this is an ENT, a medical specialist for conditions involving the ears, nose and throat. ENTs provide treatment for diagnosed obstructions involving the tonsils, adenoids and sinuses.
Even so, persistent mouth breathing may already have affected your child's bite. It may be prudent, then, to also have their bite evaluated by an orthodontist. There are interventional measures that can help get jaw development back on track and minimize future orthodontic treatment.
Finally, a child who has undergone treatment to remove nasal breathing obstructions usually reverts to nasal breathing automatically. But sometimes not: To “relearn” normal breathing, a child may need to undergo orofacial myofunctional therapy (OMT) with a certified therapist to retrain their facial muscles and tendons to breathe through the nose.
Your child's tendency to mouth breathing may not seem like a major problem. But prompt attention and treatment could prevent it from interrupting their dental development.
